Title: Condensation elimination in an injection moulding machine
Inventor: ZEPPENFELD REINHARD
IPC: B29C45/17
Filed: 1996-04-27
Abstract: A method for preventing condensation formation on the surfaces of the punch and die of an injection moulding tool involves blowing or sucking dry, preferably cold air, along the punch (2) during tool opening and into the die cavity (1) after removal of the moulding. An arrangement for eliminating condensation includes a punch (2) which moves out of the cavity (1) a certain amount during demoulding and an air supply system (3) on the punch (2) connected to a dry air supply unit (4). Air supply is governed by a control unit (5) which feeds dry, cool air to the air supply system (3) at the start of the opening cycle of the tool, maintains the air flow while the tool is open and closes it again towards the end of the closing cycle.
